Cisco C9300X-48HX-E — Catalyst 9300X 48-Port 10G Multigigabit UPOE+ Switch with Modular Uplinks
What it is
C9300X-48HX-E is a Cisco Catalyst 9300X Series enterprise access switch designed for high-performance campus networks that need multigigabit copper, very high PoE output, high-speed uplinks, and advanced stacking.
It provides 48 × 10G multigigabit RJ-45 ports, with each port supporting 100M / 1G / 2.5G / 5G / 10G, plus Cisco UPOE+ up to 90W per port. It also has a modular uplink slot for high-speed network modules and includes the Network Essentials software tier.
Why buyers pick C9300X-48HX-E (plain English)
Every access port can run up to 10Gbps: All 48 copper ports are multigigabit, making this a strong fit for high-performance Wi-Fi access points, workstations, servers, and other devices that can exceed 1Gbps.
Up to 90W UPOE+ per port: It can power demanding devices such as Wi-Fi 6/6E APs, PTZ cameras, displays, and other high-power endpoints.
Very high switching performance: The switch delivers 1.76 Tbps switching capacity and approximately 1.309 billion packets per second forwarding performance.
1 Tbps stacking: Cisco StackWise-1T allows multiple Catalyst 9300X switches to operate as one logical system with extremely high stack bandwidth.
Flexible high-speed uplinks: Rather than fixed uplinks, you choose the C9300X network module that matches your 10G, 25G, 40G, or 100G requirements.

Where it fits (and when to choose something else)
Perfect for:
- High-density enterprise campus access
- Wi-Fi 6 / Wi-Fi 6E access points
- Devices requiring more than 1Gbps
- High-power PoE endpoints
- IP cameras and PTZ cameras
- Large enterprise office networks
- Networks requiring 25G / 40G / 100G uplinks
- Customers needing very high stack bandwidth
Choose something else if:
- You don't need PoE → choose C9300X-48TX-E
- You only need 1G access ports → a standard C9300 / C9300L may be more cost-effective
- You only need some 10G multigigabit ports → consider C9300X-48HXN-E
- You need the broader Network Advantage feature set → choose C9300X-48HX-A
- You only need PoE+ rather than 90W UPOE+ → a lower-cost Catalyst 9300 PoE model may be sufficient
TL;DR
C9300X-48HX-E is a high-performance Cisco Catalyst 9300X access switch with 48× 100M/1G/2.5G/5G/10G multigigabit copper ports, UPOE+ up to 90W per port, modular high-speed uplinks, 1.76 Tbps switching capacity, StackWise-1T, and Network Essentials licensing.
